Abstract :
With the growth of cloud computing and other high-bitrate disaster recovery center (DRC) support service, DRC networks play an important role in the future networks. But the nature or man-made disaster is the main threaten of survivability. In this paper, we focus on the protection of DRC node based on contentconnectivity against disaster in disaster recovery center networks. An integer linear programming (ILP) model is proposed for that. Simulation results shows that, the proposed method has better performance to deal with node failure with less backup spectrum resources.
